Newbie question: f([1 2 3],[1 2 3])

[gnalle]

I have a function f(x,y). This could either be a funktion that I have
written myself or a Besselfunction besselj(x,y). In MatLab I can write:

f([1 2 3],[1 2 3])

This would give me a matrix that I can use to do a 3d plot

[f(1,1) f(1,2) f(1,3); ........ ]

Is there an easy solution to do the same in octave?

Will my feature be added to octave?

I have a feeling that I have asked  a stupid question. But I am somewhat
new to octave, and this is a help-list.
